El crecimiento de la potencia de procesamiento de los sistemas de computación paralelos requiere redes de interconexión de mayor nivel de complejidad y un mayor rendimiento, por lo que consumen más energía. Mayor cantidad de energía consumida conduce a muchos problemas relacionados con los costos, la infraestructura y la estabilidad del sistema de refrigeración. Los enlaces de la red contribuyen en una proporción sustancial al consumo total de energía de dichas redes. Varias propuestas se han ido acercando a una mejor administración de la energía de los enlaces. En esta tesis, aprovechamos ciertas características integradas en la tecnología actual de los enlaces para ajustar dinámicamente la velocidad de los mismos en función del tráfico. De esta manera, la red de interconexión consume menos energía cuando el tráfico es ligero. También proponemos una política de enrutamiento que tiene en cuenta la velocidad del enlace que favorece las conexiones de alta velocidad en el proceso de enrutamiento de paquetes para aumentar el rendimiento de la red cuando se despliega el mecanismo de ahorro de energía. Los resultados de la evaluación muestran que las redes que usan el mecanismo de ahorro de energía aquí propuesto, reducen el consumo de energía a expensas de un aumento en el promedio de latencia de paquetes. Sin embargo, con la propuesta de política de enrutamiento que tiene en cuenta la velocidad del enlace, nuestro mecanismo incurre en un menor aumento en el promedio de la latencia de paquetes mientras se logra un ahorro de energía similar, en comparación con otros enfoques convencionales de la literatura.
The growing processing power of parallel computing systems requires interconnection networks a higher level of complexity and higher performance, thus they consume more energy. A larger amount of energy consumed leads to many problems related to cost, cooling infrastructure and system stability. Link components contribute a substantial proportion of the total energy consumption of the networks. Several proposals have been approaching a better link power management. In this thesis, we leverage built-in features of current link technology to dynamically adjust the link speed as a function of traffic. By doing this, the interconnection network consumes less energy when traffic is light. We also propose a link speed aware routing policy that favors high-speed links in the process of routing packets to boost the performance of the network when the energy saving mechanism is deployed. The evaluation results show that the networks deploying our energy saving mechanism reduce the amount of energy consumption with the expense of an increase in the average packet latency. However, with the link speed aware routing policy proposal, our mechanism incurs a less increase in the average packet latency while achieving similar energy saving, compared with other conventional approaches in literature.

In mobile environment, how to extend the life time of mobile devices is an important issue. This thesis presents an energy conservation scheme, Maximum Unavailability Interval (MUI), to improve the energy efficiency for Power Saving Class of Type II in IEEE 802.16e. By applying the Chinese Remainder Theorem, the proposed MUI is guaranteed to find the maximum Unavailability Interval, during which the transceiver of a mobile station can be powered down. In Type II, there are three parameters: (1) sleep window, (2) listening window, and (3) start frame number. The proposed MUI only dynamically adjusts one parameter, the start frame number. The other two parameters are set according to Quality of Service (QoS) requirements of the connections. Our proposed scheme will not change them. In addition, our proposed scheme is fully compatible with 802.16e standard. We also propose a new table-based algorithm to reduce the computational complexity when solving the Chinese Remainder Theorem problem. Simulation and analysis have been conducted to evaluate and compare the performance of the proposed MUI using Chinese Remainder Algorithm and Table-based Algorithm with a brute force algorithm. Both simulation and analysis show that the proposed MUI with table-based algorithm performs better than the other two schemes.

The objective of this study is to investigate the swimming maneuvers of a fish. The experiments are carried out using the high speed camera to do motion analysis and particle image velocimetry (PIV) to do quantitative analysis between colored carp swimming in free stream and behind the step. To know how can colored crap change swimming locomotion decreasing energy consumption. The comparison of swimming locomotion and flow field structure between colored crap swimming in free stream and behind the step is a main part of this study. Colored crap use the propulsion modes of caudal fin and body undulatory motions when swimming in free stream. On the other hand, when swimming behind the step, it use pectoral fins as the main propulsion source to stay. The swimming locomotion analysis shows that the tail-beat frequency is larger than pectoral beat frequency, and the lateral body amplitudes of colored crap swimming in free stream is larger than behind the step. The qualitative flow visualization shows that the production of vortex ring between colored crap swimming in free stream and behind the step is so different. When colored crap swimming in free stream, it choose BCF mode to swim forward. When colored crap swimming behind the step, the direction of the central jet force is different from the central jet of reverse Karman vortex . Besides, we use vortex ring model calculating the value of the central jet force when it swimming behind the step. These values are close to the drag force that it stay in free stream. The experimental results indicate that colored crap know how to manipulate the interaction between the fins and the environmental flow field to decrease the energy consumption when swimming in fast flow.

The purpose of this study was to find an energy-saving trajectory for a motor-toggle mechanism. The effects of clamping forces on a motor-toggle mechanism are dynamically modeled in this study. The clamping unit used was a simple spring-damper model. Based on a real application, an impulse model associated with clamping effectiveness had to be considered for the process of clamping. A two-stage identification method also had to be developed to validate the dynamic responses of the unclamping and clamping motions. The two-stage identification method for the system parameters was carried out through a real-coded genetic algorithm (RGA) with two different fitness functions. The purpose was to improve the accuracy of parameter identification and identify the amount of saved time, both of which were obtained by the results of numerical simulations and experimentation. The point-to-point (PTP) trajectory is described by a high-degree polynomial, which satisfies the end conditions of displacement, velocity, acceleration and jerk at the initial and final times. Planning an energy-saving trajectory through the use of a high-degree polynomial for a toggle mechanism driven by a permanent magnet synchronous motor (PMSM) is quite useful. However, it was essential to find a sufficient degree for the polynomial that would produce an energy-saving trajectory. The real-coded genetic algorithm (RGA) method was employed to determine the coefficients of the polynomial, and its fitness function was the inverse of various input energy values. Comparisons of the results of the numerical simulations and experiments for polynomials of differing degrees during the whole operation of motion were analyzed. Finally, it was found that the minimum input absolute electrical energy (IAEE) value was produced when the highest-degree polynomial was used. From the percentage of relative error with respect to the input absolute electrical energy value of a trapezoidal trajectory, it was found that the percentage of relative error was -12% when the 30th-degree polynomial trajectory was used with a sufficient minimum input energy value for a single movement of the motor-toggle mechanism system. From convergent analysis, it was found that the 24th-degree polynomial was efficient in designing the energy-saving trajectory. The proposed methodology can be applied to any mechatronic system which requires the design of a minimum-energy point-to-point trajectory.

To satisfy the growing demands in the quality of services of wireless users, future 4-th generation (4G) communication systems are expected to embrace the concept of the multiple component carriers. Though the minimum service requirement can be better maintained in the rush hours with multiple component carriers, the energy consumption due to the use of additional component carriers beyond primary component carrier may be wasted in non-rush hours. However, the traditional radio resource allocation problem focuses only on optimizing the dynamic transmission power and the system performance. As a result, the key related power optimization problem remains unsolved. In this thesis, we consider a cellular system with dual component carriers. We allow the system to dynamically turn on and turn off the secondary component carrier according to the traffic load while maintain the users’ quality of service. Besides, we also compare two traditional allocation approaches, discussing their advantages and disadvantages, and show how to utilize them into green radio base stations with multiple carriers. Simulation results show that our energy-saving wireless system can successfully satisfy the users’ minimum capacity requirement, while both the blocking probability and fairness of the system can also be maintained at an acceptable level. Most importantly, we employ two different non-homogeneous Poisson arrival processes to test the energy-saving wireless system, and simulation results show that our system saves more than 40 percent than the system without carrier activation algorithm in two different scenarios, if the ratio of heavy traffic hours and light traffic hours is about 1:1.

In recent years, the Cloud computing has become an important role in our daily lives. Many companies offer their own cloud services, in fact, we have unwittingly using these cloud services, such as Google Maps and Apple multimedia services. In general, by applying the virtualization technologies, the data center is built for cloud computing to provide the computing and storage resources, as well as the software environment for users. In order to reduce energy consumption of the data center, by applying the dynamic voltage scaling and load balancing technologies, a new scheduling strategy has been proposed in this thesis to improve the system performance in the cloud computing environment. For saving energy consumption, the system voltage will be adjusted dynamically according to the utilization of each host CPU. Furthermore, the virtual machine will be migrated appropriately to achieve the purpose of energy saving and load-balancing. The experimental results show that about 4% to 14%energy can be saved by applying the proposed mechanism, and a better load-balancing can also be achieved. Some key techniques will also be discussed in the thesis.

In this study, the swimming patterns and energy-saving mechanism in fish school is numerically and experimentally investigated. The fish school phenomenon is first observed and qualitatively studied in experiment. To further investigate the energy-saving mechanism of fish school with mono-factor variable, we quantitatively characterized the wake flow structures, forces, and power consumption using numerical simulation with respect to various swimming patterns. The results show that the spatial arrangement of school and the shed vortices are highly correlated and significantly affect the performances of the thrusts and power consumption of the fish group. The low pressure suction force produced by the reverse Karman vortices shed by the upstream fish decreases form drag of the downstream fish and facilitates the undulating movement periodically. The head and tail of the downstream fish reveal negative work output at specific time step because of the low pressure region between the downstream fish assisting the body undulation This mechanism reduces the power consumption of each fish in school by 20% averagely compared with that in solo. In three dimensional simulation self-propelled cases, the results show that the average swimming velocity of the fish following case is greater than that of fish swimming in solo with the same body undulating motion. The energy-saving mechanism reveals in this work offer a physical insight into bio-inspired arrays for the underwater vehicles.

In recent years, the use of mobile wireless devices has been growing exponentially. In order to serve intense traffic such as at train stations, at airport gates, or in classroom buildings, the investigation of 5G for the next generation of mobile telecommunication has been triggered[27]. Additionally, one promising solution is the deployment of massive small cells, called dense small cell network, which can get more capacity. However, the base stations are one of the biggest contributors for power consumption. To address the power consumption challenge, the Small Cell On/Off mechanism are discussed by the 3GPP. Previous solutions for Small Cell On/Off mechanism in dense small cell network could get energy saving. In this paper, we aim to minimize the total power consumption of network while guarantee the quality of service(QoS) of all the users. First, we find that the base stations(BSs) activation problem for minimizing network power consumption is an NP-Hard problem. To address the problem and further reduce the energy consumption of massive small cells, we proposed a clustering-based scheme for Small Cell On/Off method in dense small cell network. First, the base stations are clustered based on distance, and then we discuss inter-cluster and intra-cluster separately for Small Cell On/Off mechanism. Finally, we can improve energy consumption and reduce the time complexity. Additionally, we also analysis the time complexity for proposed algorithm. Simulation results demonstrate that proposed method can further reduce the energy consumption as well as guarantee the quality of service(QoS) of all the users in dense small cell network.

With popularity of iPhone and Android phones in recent years, smartphones are becoming universal and common, and a variety of applications and plenty of commercial potential are within it. Apart from traditional dialing and text messaging, people also use smartphones to browse webpages, play games, watch online videos, use social networking services, update information of news and weather, etc. As a result, using wireless interfaces has become a trend custom. However, with the slow development of battery technology and the huge power consumption of wireless devices, the lifetime of smartphone is reduced sharply. Consequently, we propose a smart scheduling mechanism by controlling packets. We focus on the periodic applications, recording their last sync time and remember their period, so that we can predict their future sync time. We delay the DNS packet of the front application, so the distance between the applications will become closer with time. At last, they can sync simultaneously, reducing the time of wireless interfaces spent on staying in idle mode, so as to achieve the goal of energy saving. The experiment results show that energy saving is achieved in both Wi-Fi and 3G scenarios, especially in 3G. We also consider the DNS packets of non-periodic applications, making them send out with other applications simultaneously if possible.

It is important for network operators to deploy access network technology that provides vast transmission capacity and supports energy efficient operation. Passive optical network (PON) is a prominent technology in the access network technologies that provides the essential high transmission capacity, “future-proof” medium and has less energy consumption among the access network technologies. However, the worldwide deployment of PON systems still consumes a significant amount of energy. The time and wavelength division multiple access (TWDMA) PON is the next-generation architecture. The challenging issue is how to deploy time and wavelength scheduling system that is adept to control the multiple DBAs, the ALR and ONU sleeping condition. Recently, software-defined network (SDN) approach has been proposed to simplify access network control and management. With SDN programmability, the power consumption of the PON system can be reduced through dynamic network resource provisioning. With this enhanced controllability, the SDN is adept at bringing more energy-saving capabilities and enhancements to the current PON standards. Therefore, in this dissertation, the study proposes a new software-defined architecture and operation for TWDMA PON, where the author introduces the advantages of software-defined to provide inclusive energy saving both OLT and ONUs. The author proposes a new software-defined OLT and ONU architecture to provide the necessary software-defined capability to the PON system. The proposed architecture appoints SD applications to orchestrate the number of active OLT transceivers, link-rates, ONU’s (Rx) receiver sleep duration, and ONU’s transmitter (Tx) wake-up threshold according to the traffic condition. The SD programmable operations deliver a balance between OLT and ONU energy-saving, while still guaranteeing the QoS requirements.

Energy saving or carbon reduction has become one of the important issues in the world. Therefore, it is urgent to reduce carbon emissions effectively in all countries. To examine the motivation of carbon emission for firms is active or passive; this study investigates the impact of three aspects, the corporate performance, the policy and the global oil price on carbon reduction. The selected samples are the companies which had disclosed carbon emission data in Taiwan from 2012 to 2016. The empirical results show that well-performed companies do not reduce carbon emission actively. However, when the government announces the policy, companies will be forced to reduce their carbon emission. The results of this study demonstrate that the announced policy can effectively reduce the carbon emissions of the companies. It shows that the carbon reduction activities of Taiwanese companies are passive rather than active.

Factories usually use cooling tower to be the cooling equipment for air system or production cooling system. This study is to explore the way to lower energy consumption since the energy cost is increasing by using cooling tower. This study is designed to use circulating water tower in top floor reservoir replace traditional cooling tower. Separated into experimental group and control group, analyze the feasibility of using sustained water use on top floor reservoir instead of traditional cooling tower to compare each energy saving result. The study focuses on using sustained water use on top floor reservoir and the property of tap water normal temperature instead of traditional way by using cooling tower to do the research. The temperature will get increasing by heat exchange on traditional cooling tower, relatively the increasing temperature will lower chiller performance and cause power consumption. Explore the temperature into the water and volume of usage from top floor reservoir, compare performance of chiller with traditional cooling towers, and do the comparison on the power use by two circulating cooling modes. Experimental group costs about NTD 3 millions and control group costs about NTD 3.7 million, the difference is about NTD782 thousand. According to the cost variance, it shows that using water reservoir to be cooling system can totally replace traditional cooling tower, and also provide energy saving and cost saving.

The study focuses on the design of innovative leg mechanism of Quadruped robot for saving more energy. Generally, the proportion of the body weight not including the limbs is more than 50%. The load effect will intensify the tress increasing and energy consuming. The study proposes a new concept of leg mechanism that gravity balance concept and spring resistance releasing methodology are adopted. Standard gait cycle of the bionic quadruped robot can be divided into stance phase and swing phase. In the period of stance phase, most of the torque induced because of the body weight. The gravity balance theory is thus introduced. The spring arrangement and stiffness are detailed studied and calculated. While in the swing phase, the motors or actuators need only drive the leg mechanism swing a step ahead and not to considering the loading of body weight. In this case the former assigned spring force will become a resistance force to increase the motor load. The switcher for releasing the extra spring force is the another study issue and some of the cam-linkage switch device is created and evaluated using ADAMS. The current research results propose a 3.5% energy saving than no-spring case. Furthermore , advanced improvement of weight and inertia decreasing of cam and linkage will be expected to reach a 73% energy saving efficiency.

IEEE 802.16e defines the Power Saving Mechanism（PSM）which allows a mobile station （MS）to stay in sleep mode for saving its power consumption. However, it is still an open question to develop a good Base station（BS）scheduling mechanism which schedules several MSs for data transmission by taking into consideration their sleep requests. This paper aims at developing a scheduling mechanism which improves the bandwidth utilization of BS and saves the energy consumption of several MSs. Based on the bandwidth requirements and the delay constraints of several Unsolicited Grant Service（UGS）connections, the developed scheduling mechanism arranges the sleep and listening windows for each connection, avoids the transmission collision and makes good use of the bandwidth resource. Simulation study reveals that the proposed mechanism improves the WiMAX performance in terms of the network throughput and the energy consumptions of MSSs.

Cloud computing provides the highly scalable and maintainable computing resources for industrial applications and provides an important opportunity for information industry. In order to integrate the system resources, save energy consumption, and meet the user's requirements, Dynamic Voltage Frequency Scaling (DVFS) and virtual machine migration technologies were widely discussed for effectively reducing the energy consumption. Dynamic voltage and frequency scaling is to use the system slack time to reduce the system voltage, so as to reduce energy consumption, but the execution time of the work will be prolonged. It is an important issue to effectively adjust the operating voltage of each job, and to meet the users’ requirements. In recent years, many researchers proposed a number of different scheduling algorithms based on dynamic voltage frequency scaling technique to solve this problem, but most of those studies applied static scheduling methods which limited to the known execution order of tasks. A dynamic scheduling mechanism in the cloud computing environment, called Extenics-based Dynamic Voltage Frequency Scaling (E-DVFS) mechanism has been proposed in this dissertation. In the cloud computing environment, applying virtualization technologies, according to the expected execution time provided by the user, an extenics relational function can be built to calculate and predict the completion time of the job and the working voltage. Moreover, the dynamic virtual machine migration technique has been applied to further reduce energy consumption and meet the Quality-Assurance (QA) requirements. CloudSim simulator is used in this research to verify the effectiveness of the proposed E-DVFS mechanism. Simulation results show that the system can meet QA requirements, and total energy consumption of servers can be reduced about 13% ~ 25 %.

The well development of Mobile Communications Networks (MCNs) causes the dramatically increasing of the smart devices. The smart devices such as wearable devices have limited battery lifetime so that it has the better choice to use the NB-IoT protocol to transmit the small data for the purpose of power saving. The wearable devices are also able to make the voice call through the VoLTE. Therefore, the interworking of the NB-IoT and LTE networks is necessary in the future. The power saving issue is generated if both NB-IoT and LTE interface of the UE attach to the networks. We propose the Protocol to Protocol Switching Mechanism (P2PSM) to enable the dual-mode UE to be supported in the NB-IoT and LTE interworking network and reduce the power consumption. The analytical models and simulation experiments are conducted to investigate the performance of the P2PSM mechanism. Our study shows that the proposed P2PSM mechanism can efficiently reduce the power consumption of the UE.

Abstract On the past few years, the shortage of the energy happened and climate changed violently. After Kyoto Protocol was signed, every country recommends energy-conservation and carbon reduction actively. These things have been impeled compatriots to realize “ The energy-conservation of environmental protection” is an unavoidable trend and responsibility in environmental consciousness. Using the technology of regenerated energy to reduce the energy in wasteing and reduce the energy to strike the environment. It is the goal to promote internationally actively at present. For a school, how to reduce the cost of plant maintenance and prevent the electric energy from wasting and reducing the expenditure of the electric rate effectively. These are important subjects at present. This study apply the projcet in a University of Science and Technology for a case study. We apply data mining to find out the influences of environmental protection energy-conserving effect and analyze to power consuming relevance of trend. Besides, using EXCEL to analyze, draw trend picture and introduce some University of Science and Technology in a growing factor adopt with electricity. Because of energy-conserving countermeasure that answer and the case verifies the energy-conserving effect through succeeding. Research reveals that the energy-conserving effect for an environmental protection is influential to the power consuming trend of the school, carrying out the energy-conserving plans can slow down the trend of power consuming with the electricity effectively.
